Advanced Energy Materials, EarlyView.A catalyst‐free solid‐state Li‐O2 battery achieves current‐driven four‐electron Li2O formation, delivering simultaneous high‐energy and high‐power operation with 1032 Wh·kg−1 and 374 W·kg−1 in a single cell. ABSTRACT Li‐O2 batteries offer a compelling pathway toward next‐generation energy storage owing to their ultrahigh theoretical energy density ...

Applied Economic Perspectives and Policy, EarlyView.ABSTRACT Increased frequency of extreme weather events, particularly droughts, threatens grassland farming by destabilizing yields and farms' economic viability. We examine, theoretically and through numerical simulations, how sown plant diversity (natural insurance) influences the attractiveness of indemnity and drought index insurance (formal ...
